Question

Match the following list and choose the correct combination.

List-A	List-B
(A) Oxidoreductases	(i) Linking of two compounds
(B) Isomerase	(ii) Removal of groups from substrates
(C) Ligases	(iii) Inter conversion of isomers
(D) Lyases	(iv) Dehydrogenation
	(v) Hydrolysis

• A. A- (iv), B- (i), C- (iii), D- (ii)
• B. A- (iv), B- (iii), C- (i), D- (ii)
• C. A- (iii), B- (iv), C- (ii), D- (v)
• D. A- (ii), B- (v), C- (iii), D- (i)

Answer 1

The correct option is B A- (iv), B- (iii), C- (i), D- (ii)

Oxidoreductases catalyse transfer of electrons i.e., hydride ions or H atoms. Hence, these enzymes with add oxygen or remove hydrogen atoms from the substrate.
Isomerases catalyze transfer of groups within molecules to obtain their isomers.
Ligases catalyze synthesis of one compound by two or more substrates via formation of C-C, C-S, C-O, and C-N bonds by. The reaction is condensation reactions and utilizes ATP.
Lyases catalyze addition of groups to double bonds to form single bonds or formation of double bonds by removal of groups.
So, the correct answer is option B.
